Zhang Chuge felt that he was unable to argue, and after saying a few words, he stopped talking.

"Could it be that the murderer is Gong Huarong?"

The suspected motive of the case suddenly returned to the beginning.

"The reason why we suspect that the murderer is Gong Huarong is because the murderer and Ju Yingjie were once boyfriend and girlfriend. After Gong Huarong's death, the relationship between the two became a bit complicated. Maybe Gong Huarong

I hold a grudge and feel that because of Ju Yingjie's presence, my relationship with this new girlfriend is inaccessible."

Jin Jiajia nodded but said nothing.

"But the surveillance video has been captured."

Zhang Chuge's words refuted all Chen Ziyan's speculations.

"What should I do? Is it difficult to keep this case in a file?"

Jin Jiajia is very helpless now, especially hoping that Liu Xuan can come out and take a bath at this time.

"I think if this case wants to be solved, only Liu Xuan can solve it."

Qin Siyu came to a conclusion on the side, but Chen Ziyan rolled his eyes.

"Wait a minute, let me think about it carefully, this problem shouldn't be that difficult."

Chen Ziyan always felt like he had a clue.

The cinema where Gong Huarong watched the movie was actually only a 20-minute walk away from the deceased's neighborhood.

"Could it be that Gong Huarong suddenly came out in the middle of watching the movie... went to Ju Yingjie's home, killed Ju Yingjie, and then returned to the cinema to continue watching the movie?"

Chen Ziyan sat at the table and raised his eyebrows.

"Who knows, but it's dark in the cinema, so no one knows what's going on."

"If Ju Yingjie suddenly came out in the middle of the movie, his girlfriend was concentrating on watching the movie and did not notice it, including everyone else in the cinema who was concentrating on watching the movie. Gong Huarong could have gone out through the back door of the cinema

, and then walked for 20 minutes to the community where the deceased lived, and then killed Ju Yingjie, and then spent 20 minutes to return... In this way, the time of going back and forth was almost an hour, while running

If we go forward, we can control it to 45 minutes."

Chen Ziyan repeatedly measured the distance on the map.

"According to the running speed of an adult man, within 45 minutes, he ran from the cinema to the deceased's home, killed the deceased and then returned to the cinema... This is not an impossible thing, and usually it is

The running time of the movie is more than one and a half hours, and there are very few movies that are one hour long."

Chen Ziyan specially took out his mobile phone and searched for several recently played movies on it.

Except for one movie whose playing time is 100 minutes, the playing time of other movies is more than 110 minutes, and the longest one can be 130 minutes.

"Including current movies, there will actually be an additional advertising space before the screening. This time is estimated to be five to ten minutes... After counting this time, the actual screening time of a movie is at least 115 minutes. In

It would not be difficult to spend 45 minutes during this period to go to the deceased's home and kill him."

Chen Ziyan said calmly.

"But the only problem is how to leave the cinema and return without disturbing others."

Chen Ziyan said suddenly.

Went to the theater again with Jin Jiajia, this time Chen Ziyan did not go in directly, but walked around the theater.

This cinema is set up above a merchant. The three floors below are for shopping and dining. Most of the fourth floor is dedicated to the cinema, and the rest is KTV.

"But at the beginning, the staff member once said that the employee channel only needs to swipe the employee ID card to enter..."

Chen Ziyan turned around and found that there was no garbage passage opening.

Apart from the main entrance, there is only this entrance where you need to swipe employee ID cards.

I went to push it, but the entire iron door didn't move at all, and the magnetic suction on it was tight.

"This kind of door is usually energized. After the electricity is energized, a magnetic attraction is generated, and then the door can be attracted. When the employee ID card is swiped, the power will be cut off, so the magnetic force will disappear and the door can be opened."

He looked up at the door locking device on the door panel.

"Can it be vandalized?"

Jin Jiajia took a look.

"It's okay, you just need to cut off the power, and the door will open naturally."

Chen Ziyan specially brought a chair over and climbed up to take a closer look.

"There are no tool scratches on it, and the wires are well connected."

Since most of the entire device is set up inside the door frame, there are not many exposed areas.

Therefore, it is not an easy task to cut off the power to the door and still power it on smoothly.

"By the way, what does Gong Huarong do?"

Chen Ziyan raised his eyebrows fiercely.

Jumped off the chair.

"Wait a minute, let me ask Zhang Chuge."

The news from Zhang Chuge spread quickly, and Gong Huarong's work information was soon received.

He is the project manager of an IT company in this city.

Jin Jiajia looked at the message sent by Zhang Chuge on her phone and said.

"It is said that this IT company is very famous in this city, and the recruitment standards are also very high."

Jin Jiajia held her chin and said.

"In other words, Gong Huarong entered this company through a back door?"

Chen Ziyan didn't think much and came to such a conclusion.

"Well... there is a certain possibility, but Zhang Chuge also sent a message that is more interesting. Although Gong Huarong did not do well in the college entrance examination, and was admitted to a junior college in the end, he not only gained a lot during his time in university

Awards, and many personal inventions..."

Jin Jiajia turned the phone screen around.

"That is to say, it is not difficult for Gong Huarong to solve this problem."

Chen Ziyan particularly noticed that one of the personal awards was related to security door anti-theft measures and emergency escape plans.

Although there is no detailed label, you can already imagine what it is related to.

"It seems that Gong Huarong should be investigated carefully."

…

Gong Huarong was sitting on the chair, wearing trendy fashion brands, tall figure and handsome face.

Jin Jiajia was stunned at the first sight and was given a fierce roll by Chen Ziyan.

"I called you here last time because I was investigating this murder case. I hope you can cooperate."

Chen Ziyan said sincerely, spreading the notebook on the table.

"I don't know where the police investigation is now. I have been paying attention to this matter recently. Although Ju Yingjie and I have broken up, we have been together for such a long time. It is impossible to say that we have no feelings at all.
